To all whom t may concern:

Be it known that I, ALBERT E. READE, a citizen of the United States of America, residing at Petersburg, in the county of Dinwiddie and State of Virginia, have invented certain new and useful Improvements in Acetylene-Gas Generators', of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to an acetylene gas generator and has for its principal object the production of a 'simple and eliicient means whereby the carbid carried thereby may be immersed in a quantity of'water for' generating gas yas the supply within the bell'y becomes exhausted.

Another object of this invention is the production of a simple and eflicient guide means for the bell which will positively retain the bell in its central position and facilitate the passing thereof into the well.

Another object of this invention is 'the production of a simple and eflicient means for retaining the carbid basket in its correct With these and other objects lin view, this invention consists of certain novelcombinations, constructions7 and arrangements of parts, as will be hereinafter fully described and claimed. Y

Tn the accompanying drawing: Figure 1 is a detailed perspective view of the acetylene gas generator. Fig. 2 is a central vertical section of the acetylene gas generator', Fig; 3 is a fragmentary'side elevation of the upper portion of the generator, illustrating themanner in which one of the guide rods is supported. Fig. 4 is a section taken on the line t--fl of Fig. 2. Fig. 5 is a .side elevation of the carbid basket and the'tube for supporting the same. Fig. 6 is a fragmentary sectional view through a slightly modified form of the invention, illustrating the manner in which one of the guide rods is supported. Fig. 7 is a detailed perspective view of the lug used in supporting the rod, as disclosed in Fig. 6.

Referring tothe accompanying drawing by numerals 1 designates the well of the acetylene generator having the ared or funnel-like upper end 2. The bell 3is adaptedto ft within the well 1, as shown clearly in Fig. 2. This bell 3 has the ears 4 soldered upon its upper ends, the outer ends of these ears being carried at a spaced distance above the bell 3 whereby the bell may pass into said well toa greater depth than would be the case if the ears were straight. The guide rods 5 extend through the apertures 6 formed in the outer ends of the ears 4 so as to guide the upper end of the bell 3 when the same moves upwardly or downwardly within the well l. The lower ends of these guide rods 5 pass through the ared upper end ofthe well land pass through.

the lugs 7 carried by means of the rivet heads 8 in engagement with the well 1.. The

lower ends of the guide rods 5 areheld in engagement with these lugs 7 by means of the 'solder 9 which'is positioned around the lower ends of the rods 5 and upon the upper portions ofthe lugs 7. Therefore, while the rods 5 are held in fixed engagement with the lugs 7 they will also be braced at a spaced distance from their end portions by means of the flared upper end 2 of the well 1, and in this'manner the rods will be positively retained 4in vertical positions and in parallel spaced relation relative to each other.

The short pipe lO'eXtends through the upper portion of the bell 3 and has transverse openings 11 communicating with the inner portions of the bell 3. y The flexible tubing12 or short conveying pipe may be passed over the `upper end of the short pipe `10soas to conduct thel gas from the inner portions of the bell to any desired. place. Thev rod 13 passes into the lower end of the short pipe 10 and this short pipe is crimped into engagement with the rod so as to carry .a quantity of solder 14 for X- edlyl retainingvthis rod 13 in engagement with the' pipe 10'.v Thisrod .extends for considerable distance belowthe lower' end of the pipe lO'andupon thisrod there is detachablyv mounted a tube l5. The upper end of this tube 15 engages the crimped lower'end of the pipe l0 and is held in a detachable position by means of the nut 16 threaded into engagement with the lower end of the rod 13. A plate 17 is, soldered, as shown at 18, upon the tube l5 and is provided with a cylindrical screen 19 held in fixed engagement therewith in any suitable manner, such for instance as by solder, thereby forming a carbid basket. This basket is carried uponV the tube,intermediate its ends and adja- Y cent the Vcentral inner portions of the bell 3. This carbid basket is adapted to contain a quantity of carbid as disclosed in Fig. 2 and therefore when the bell passes downwardly into the well, the carbid will be immersed in the water, as shown in Fig. 2. As a consequence, a fresh quantity of gas will be generated which will pass into the upper portion of the bell and through the apertures ll into the pipe 10`and thence to a desired place, by means of the tubing l2. If more gas is generated, the bell 3 will be raised so as to ride upon the vertical rods 5 until the carbid is moved completely from the water and the generation of the gas discontinued.

By referring to Figs. 6 and 7, it will be seen that the Well 1 is provided with lugs 7 having threadedl openings 20 formed therein. These lugs 7 are carried by the headed rivet 8 in a manner similar to the lug disclosed in the preferred form. The

lower ends of the vertical rods 5 are thread-v ed as shown at 21 so as to thread into the openings 20 formed in the lugs 7. By this construction, it will be seen that the solder as shown at 9 in the preferred form maybe eliminated inasmuch as the lowerends of the rods 5 will be positively held against accidental displacement by passing in the lugs 7. j Y

From the foregoing description it will be seen that a very efiicient acetylene gas generator has been produced wherein the carbid basket is carried so as to be easily immersed when it is necessary to provide a fresh supply of gas, and in which the several portions are so carried as to form efficient guides for each other for allowing the device to eiiciently operate when necessary;

W'hat I claim is l. In an acetylene gas generator, thecombination of a well, a bell reciprocally mounted within said well, a short pipe carried by and extending through the upper portions of said bell, said short pipeprovided with apertures, adjacent the inner upper portions of said bell, a depending rod carried by the lower portions of said short pipe, a tube carried upon said rod, means for detachably retaining said tube upon said rod, a carbid basket ixed upon said tube, whereby when said bell moves downwardly into said well carbid carried by said basket may be immersed thereby generating gas, said short pipe being adapted to allow gas to escape from said bell.

2. In an acetylene gas generator, the combination of a well, a bell reciprocally mounted within said well, a short pipe carried by and extending through the upper portions of said bell, said short pipe provided with apertures adjacent the inner upper portions of said bell, said short pipe having a frustoconical lower end, a rod extending into said frusto-conical end of said short pipe, a filler means carried. within said frusto-conical end, whereby said rod will be supported, said rod having a threaded lower end, a tube positioned upon said-rod, a nut removably carried by the threaded end of said rod, and engaging the .lower end of said tube, where* by said tube is removably supported, and a carbid basket carried by said tube.

. 3. In anacetylene gas generator, the combination of a Well, a bell reciprocally mounted within said well, a short pipe carried by and extending through the upper portions of said bell, said short pipe provided with apertures adjacent the inner portions of said bell, said short pipe having a frusto-conical lower end, a rod extending into said frusto-conical end, a. iller means carried within said frustoconical end, whereby said rod will be supported, said rod having a threaded lower end, a tube positioned upon said rod, a carbid basket carried by said tube, a nut carried upon the threaded Vend of said rod, whereby said tube will be removably retained upon said rod, said nut being adapted to force said tube irmly upon said frustoconical end of said short pipe, whereby said frusto-conicalrend will wedge within said tube, thereby retaining said tube in a binding engagement with said nut for preventing said nut from accidentally disengaging said rod.

In testimony whereof I hereunto aiix my signature in presence of two witnesses.
